Maps of the Regions and Cities of Japan

Japan is divided into 5 main geographical divisions: Hokkaido, Honshu, Shikoku, Kyushu and Okinawa. The main island of Honshu is further divided into 5 regions: Tohoku, Chubu, Kanto, Kinki and Chugoku. The administrative system is divided as follows: Tokyo To (metropolis); Hokkaido Do (circuit); Osaka Fu, Kyoto Fu (urban prefectures); 43 Ken (prefectures). This system was introduced in 1888, with Tokyo being designated as a metropolis in 1943.
